Merged requested to merge mutluler/Authenticator:add-aegis-import into master
This MR add support for importing and exporting json files from the Aegis Android app. There are still some todos in the source code but I don't intend to fix them in this MR. I think, they are for reference for later commits/MRs.
Thanks for your review and time!
This MR fixes #149 (closed) .
